The Neotropical goblin of the new genus Varioonops (Araneae, Oonopidae)

ANGELO BOLZERN1 AND NORMAN I. PLATNICK1

ABSTRACT A new genus, Varioonops, is established for a group of species characterized by sexual dimorphism in morphology (with a dorsal scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. The closest relatives of the new genus appear to be three similar, but as yet undescribed, Neotropical genera that share those characters, but the members of Varioonops are united by a putative synapomorphy that does not seem to occur in those undescribed groups: a granulated sternum. Attention is drawn to the cymbial cone, a structure (possibly a receptor) found near the tip of the cymbium in Varioonops, members of the Orchestininae, and at least some soft-bodied members of the Oonopinae. A total of 23 new species are described: V. cafista (the type species), V. velsala, V. montesta, V. spatharum, V. poas, V. varablanca, V. tortuguero, V. veragua, V. heredia, and V. girven from Costa Rica, V. ramila and V. sansidro from Costa Rica and Panama, V. funator and V. cerrado from Panama, V. edvardi and V. sinesama from Colombia, and V. yacambu, V. trujillo, V. pittieri, V. chordio, V. parlata, V. potaguo, and V. grancho from Venezuela.

INTRODUCTION Through focused investigations of the family Oonopidae by the many participants in the goblin spider Planetary Biodiversity Inventory (PBI) project, several new genera and numerous new species have recently been described from the Neotropics. The northern Neo- tropics clearly constitute one of the hotspots of oonopid diversity, and most of the ground- dwelling species found there are microdistributed (i.e., are short-range endemics).

Copyright © American Museum of Natural History 2013 ISSN 0003-0082 2 American Museum Novitates No. 3791 taxa, including even congeneric species, can often be found at a single site (Platnick and Dupérré, 2012), and the taxa placed here as members of the new genus Varioonops fit that pat- tern well. Of the 23 species treated below, found from Costa Rica to Venezuela, only four have been collected in more than two provinces. Multiple species of Varioonops have been found sympatrically at several localities; in most cases, the sympatric species belong to different spe- cies groups within the genus, but there is one exception. Two members of the tortuguero group, the new species V. ramila and V. veragua, have both been taken in the Veragua Rainforest at Los Gigantea in Limón, Costa Rica. Recent considerations of oonopid monophyly and interrelationships (Burger and Michalik, 2010; Platnick et al., 2012a) have resulted in the recognition of three subfamilies of goblin spiders, the Orchestininae, Sulsulinae, and Oonopinae. Based on the 3-3-2-2 tarsal organ recep- tor pattern (figs. 23–27), the lack of a heavily sclerotized sperm duct in the male palp (fig. 129), and the clumped eye arrangement (fig. 123), Varioonops belongs to the Oonopinae. Basal inter- relationships within that huge subfamily remain poorly resolved, but one large group of genera, the gamasomorphines, are united by the putatively synapomorphic presence of a sperm pore on the epigastric scutum, far in advance of the epigastric furrow (Platnick et al., 2012a). That character is present in Varioonops. Most gamasomorphines also differ from the soft-bodied, non-gamasomorphine members of the Oonopinae in having lost an oblique, unsclerotized strip on the ventral surface of the basal segment of the anterior lateral . The presence of that strip may be a synapomorphy of the entire superfamily , but if so it has appar- ently been lost in all gamasomorphines other than Niarchos Platnick and Dupérré (see Gris- mado et al., in press); that strip is not found in the members of Varioonops. Although most gamasomorphines are hard bodied, with dorsal abdominal scuta present in adults of both sexes (although not in juveniles), the members of Varioonops are sexually dimorphic in that respect; males have a dorsal scutum on their patterned abdomen, but females do not (figs. 126, 137). This kind of sexual dimorphism has been reported in two groups of gamasomorphines. It is found in some members of the Dysderina complex (Plat- nick and Dupérré, 2011a, 2011b), and in all members of the Scaphiella complex (Platnick and Dupérré, 2009b, 2010a, 2011b, 2011c; Bonaldo et al., in press), and even in one genus of the related family Orsolobidae (Ott et al., 2013). However, Varioonops does not appear to be a member of either of those gamasomorphine complexes. The carapace shape, sternum shape, and leg spination suggest a closer relationship to the Dysderina complex, whereas the patterned abdomen is shared only with Pescennina Simon, a member of the Scaphiella complex (Platnick and Dupérré, 2011c). The members of both the Dysderina and Scaphiella complexes, however, all share an apomorphic feature of palpal morphology, the fusion of the palpal bulb with the cymbium. This feature has seemingly been acquired independently in some soft-bodied oonopines (Platnick and Berniker, 2013a, 2013b), but it does not occur in Varioonops. However, there are three other new Neotropical groups that are currently being described (Bolzern, in prep.; R. Ott, in litt.) whose members share at least the following characters with those of Varioonops: sexually dimorphic scuta (with females lacking dorsal abdominal scuta), 2013 BOLZERN AND PLATNICK: VARIOONOPS 3 a patterned abdomen, and a separate palpal cymbium and bulb. Thus, these groups together seem to constitute a third complex of sexually dimorphic Neotropical gamasomorphines. Within this complex, the members of Varioonops share two features also found in one of the undescribed genera that is likely to represent their sister group: a uniquely broad, triangular projection, bearing distally flattened setae, on the anterior portion of the male endites (figs. 7, 67–69) and a cluster of distally filiform glands situated at the base of the anterior genitalic process of females (figs. 44, 103, 157, 305, 472, 488). The species assigned here to Varioonops, however, all have a distinctly granulated sternum (figs. 4, 34, 64, 94, 378, 415, 462, 484) that appears to be unique to, and synapomorphic for, this group alone. While studying the male palps of Varioonops with scanning electron microscopy, we noted a peculiar structure near the tip of the cymbium (figs. 9, 70, 285, 363, 411, 458). It was detected in almost all the species, but on some specimens, in some positions, it can be fully obscured by the surrounding setae. This cymbial cone is situated on the dorsoretrolateral side of the cymbial tip. It may be a receptor, or a secretory structure, as there is often an opening visible at the tip. In previously published illustrations, we have detected the cymbial cone only in two African species of Orchestina Simon described by Henrard and Jocqué (2012: figs. 165, 166, 252, 253), but it is also apparent in images of an as yet undescribed South American species of Orchestina and members of two undescribed groups, as well as possibly in members of the soft-bodied oonopine genusNeotrops Grismado and Ramírez (2013). Given this relatively widespread distribution within the family, the cymbial cone is unlikely to be a synapomorphy of an oonopid subgroup, but the presence or absence of the character needs to be documented in other oonopid genera, especially those of the subfamily Sulsulinae, as well as in the other families of dysderoids. Among other unusual characters of Varioonops are the “false claws,” paired setae situated at the tips of tarsi III and IV that have a heavily sclerotized, enlarged, claw-shaped tip (figs. 21, 54, 448). Similarly modified setae have been found in several other groups, including some rather distantly related genera (Grismado et al., 2011; Ubick and Griswold, 2011; Platnick et al., 2012b; Bonaldo et al., in press). Also notable is a peculiarly short, modified seta situated distolaterally on metatarsi I–III (figs. 56, 88, 117). The position of these setae suggests that they may be involved in proprioception; differently shaped, modified setae can be found in the same position on members of other genera, including Orchestina (see Henrard and Jocqué, 2012: figs. 559, 560), Melchisedec Fannes (2010: figs. 42, 43), and Escaphiella Platnick and Dupérré, (2009b: fig. 42), but setae with this particular shape have been detected to date only in Vari- oonops and a closely related, undescribed group of species. So far as we have been able to determine, no oonopids previously described from the areas occupied by Varioonops appear to belong to the genus; apparently members of the group were never found by Arthur Chickering during his extensive fieldwork in Panama, and no specimens are known from the areas in southern Panama where most of his collections were made. Some informal species groups can be recognized, based primarily on the shape of the male embolus and conductor, but we are able to assign only 14 of the species to such groups; the groups are reflected in the key to species provided below. 4 American Museum Novitates No. 3791

The cafista group (containing V. cafista and V. velsala) and the montesta group (con- taining V. montesta, V. poas, and V. spatharum) are known only from Costa Rica. The tortuguero group (containing V. ramila, V. tortuguero, V. varablanca, and V. veragua) and the sansidro group (containing V. heredia and V. sansidro) are also primarily Costa Rican, but each contain one species that extends into northern Panama. The yacambu group (containing V. pittieri, V. trujillo, and V. yacambu) is endemic to Venezuela. The members of these groups are united by the following details: the cafista group by the evenly curved embolus with a distinct plate-shaped tip in combination with a distinct opening on the conductor (figs. 12–15, 150), the montesta group by an embolus bent about 90° prolaterad with an opening skewed dorsally and a distinct conductor with a backward-pointed spur (figs. 163, 165, 178, 193), the tortuguero group by an embolus tip abruptly bent prolaterad and a simple, elongated conductor originating prolateroventrally at the embolus base (figs. 72, 73, 208, 242, 253), the sansidro group by a basally strongly bent and more distally moderately bent, smooth embolus in combination with a very short, flat, triangular con- ductor (figs. 270, 272, 287), and the yacambu group by the broadly fused base of the embolus and conductor (figs. 393, 409, 418). The remaining species are more enigmatic. The male of V. girven resembles those of the montesta group in having the embolar opening directed dorsally, but the conductor more closely resembles those of the sansidro group. Due to their distinctively different bulb mor- phologies, V. funator and V. cerrado from Panama do not fit into any of the delimited groups. Females of V. edvardi (figs. 364–367) and V. sinesama (figs. 368–375), the only species known from Colombia, have similar internal genitalia, but in the absence of males of the latter species, we prefer not to group them. Members of the Venezuelan species V. chordio (figs. 428–442) most closely resemble those of the cafista group in general bulb and embolus shape, and even share with them what seems to be a distal opening on the conductor (similar to the one reported in species of the soft-bodied oonopine genus Neotrops by Grismado and Ramírez, 2013). The remaining three Venezuelan species are problematic: V. grancho (figs. 376–382) is known only from a single female from an uncertain locality, V. potaguo (figs. 474–488), the smallest species in the genus, resembles species of the yacambu group but also shows distinct differences, and V. parlata is so markedly different, with fewer sternal granulations (figs. 446, 462), that it might represent either the sister group of all the other species, or just a highly autapomorphic member of the genus. Our methods generally follow those of Platnick and Dupérré (2009a); only differences from the males (other than the obvious lack of male endite and scutal modifications) are mentioned in the descriptions of the females. Some females were digested with enzymatic contact lens cleaner rather than pancreatin, with comparable results. Scans were taken from coated or uncoated right male palps, and the images were flipped for consistency. All measurements are in mm; high-resolution versions of the images, a sortable version of the geocoded locality data, and a distribution map for each species will be available on the PBI website (http://research. amnh.org/oonopidae). The species descriptions are arranged by the informal species groups and then geographically, from Costa Rica south to Venezuela. 2013 BOLZERN AND PLATNICK: VARIOONOPS 5

Varioonops, new genus Type Species: Varioonops cafista, new species. Etymology: The generic name refers to the colored and patterned abdomen (Latin varius = “variegated, marked with contrasting colors”), which is unusual among oonopids, and is masculine in gender. Diagnosis: Members of this genus are similar to species of the Dysderina and Scaphiella complexes in their sexual dimorphism, with a dorsal abdominal scutum present in males (where the dorsal and epigastric scuta are not fused), but absent in females. They differ from all those species in having the surface of the sternum granulated (figs. 4, 34) and from all those except the members of Pescennina in having a highly patterned abdomen. In addition, males differ in having the cymbium and bulb not fused and by the uniquely broad, subapical, trian- gular projection on the endites (figs. 7, 67). Females differ in having a very short postepigastric scutum without lateral platelets or extensions, almost as wide as (but not fused to) the epigas- tric scutum (figs. 137, 139), the epigastric scutum completely surrounding the pedicel (figs. 138, 155), an indistinct epigynal area (figs. 139, 154), and a cluster of filiform glands at the base of anterior genitalic process (figs. 44, 103, 157).

Species from Costa Rica and Panama The cafista group Varioonops cafista, new species Figures 1–60, 121–142 Types: Male holotype, one male paratype, and two female paratypes from montane forest litter taken at an elevation of 1300 m at Cacao Field Station, Guanacaste, Costa Rica (Feb. 12, 1996; R. Anderson), deposited in AMNH (PBI_OON 49156). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Males differ from those of the other species in having a moderately but evenly curved, tube-shaped embolus with a distinct tip (fig. 14, 131) in combination with a narrow, flat, short, tube-shaped conductor that has a distinct opening (figs. 13, 15). Females differ from those of all other species in having an anterior genitalic process with an only moderately enlarged apex and an unconvoluted, club-shaped posterior genitalic process distally bearing suboval glands (figs. 43–45, 141, 142). 2013 BOLZERN AND PLATNICK: VARIOONOPS 11

Varioonops velsala, new species Figures 143–157 Types: Male holotype, male paratype, and two female paratypes (only one female prosoma present) taken at an elevation of 400 m on the southwest trail at La Selva, Heredia, Costa Rica 22 American Museum Novitates No. 3791

(Mar. 2, 2002; D. Chandler), deposited in INBIO (males: PBI_OON 31011; females: PBI_OON 31040); also two female paratypes collected at La Selva, Heredia, Costa Rica (June 25, 1999, C. Víquez), deposited in INBIO (PBI_OON 31039). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Males resemble those of V. cafista in having a moderately but evenly curved, tube-shaped embolus with a plate-shaped tip (fig. 150) but have a long, straight, tube-shaped conductor with a rounded opening (rather than a narrow, flat, short, tube-shaped conductor with a pointed distal end). Females differ in having a moderately ventrodorsally convoluted posterior genitalic process with a blunt distal end, rather than an unconvoluted, club-shaped posterior genitalic process (figs. 156, 157). Male (PBI_OON 31011, figs. 143–150): Total length 1.42. Sternum microsculpture every- where but front, at level of coxae moderately less microstructure, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum straight (in anterior view). Postepigastric scutum with posterior margin concave. Leg spination: femur I p0-1-1; tibiae: I v4-2-2; II v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Sperm pore circular. Embolus tube-shaped, elongated, evenly prolaterad curved, retrolaterally with longitudinal keel, tip with irregular oval opening and broad, elongated, distally moderately denticulate plate; conductor straight, tubular, almost as long as embolus, distally with round opening (collapsed in SEM, fig. 149). Female (PBI_OON 28114, figs. 151–157): Total length 1.64. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Median protrud- ing part of large genital plate longer than wide; anterior genitalic process stalked, bulbous, with moderately enlarged apex, moderately shorter than posterior genitalic process; field of filiform glands on small basal plate of anterior genitalic process conspicuous; posterior genitalic process moderately convoluted, tube-shaped duct, distally blunt, laterally with distinct glands (fig. 157).

The montesta group Varioonops montesta, new species Figures 158–172 Types: Male holotype, male paratype, and female paratype from cloud-forest litter taken at an elevation of 1750 m at the Estación Biológica Mongteverde, 10.31472°N, 84.79694°W, Puntarenas, Costa Rica (June 15, 2001; R. Anderson), deposited in AMNH (males: PBI_OON 31072, female: PBI_OON 31078). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Males resemble only those of V. spatharum (fig. 178) and V. poas (fig. 193) in having a tube-shaped embolus, bent approximately 90° prolaterad with an opening skewed dorsally and a distinct conductor with a broadened, flat base and distally with a long, back- ward-pointing spur (also present but short in V. cerrado, fig. 343). They differ in having a simple pointed distal tip of the conductor (rather than broad and hook shaped in V. poas or elongated and hook shaped in V. spatharum). Females can be separated from those of all other species by the short anterior genitalic process and the distinctly convoluted, distally spherically enlarged posterior process (fig. 172). Male (PBI_OON 31072, figs. 158–167): Total length 1.75. Sternum microsculpture medi- ally and in furrows, surface evenly, finely granulated. Anterodorsal margin of epigastric scutum straight (in anterior view). Postepigastric scutum with posterior margin straight (fig. 161). Leg spination: femur I p0-1-1; tibiae I, II v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Sperm pore oval. Cymbial cone basally broad, distally narrow, tube shaped, protruding. Embolus tube shaped, elongated, curved ventroprolaterad, retrolaterally with longitudinal keel and furrow, tip with simple oval opening and distally elongated, subrectangular plate; conductor proximally broad, lamelliform, long, triangular, distally pointed with distally originating, long, backward-directed, grooved, pointed spur, spur as long as lamelliform part of conductor. Female (PBI_OON 31078, figs. 168–172): Total length 1.94. Leg spination: femora: I p0-1- 1; II p0-0-1; tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Posterior genitalic process moderately visible through postepigastric plate. Median protruding part of large genital plate longer than wide; anterior genitalic process club shaped, with moderately enlarged apex, much shorter than posterior genitalic process; filiform glands on small basal plate of anterior genitalic process inconspicuous; posterior genitalic process long, convoluted duct with subspherical, enlarged distal end.

Varioonops spatharum, new species Figures 173–187 Note: Males and females have not been collected together, but are a good match in somatic morphology (e.g., microsculpture on the sternum, eyes, size); a female and a male were col- lected at La Selva in February 2001 and 2002, respectively. Type: Male holotype taken at an elevation of 2000 m at a site 6 km ENE of Vara Blanca, 10.18333°N, 84.11666°W, Heredia, Costa Rica (C. Víquez; Apr. 15, 2002), deposited in INBIO (PBI_OON 31104). Etymology: The specific name refers to the embolus tip shape, in prolateral view, which resembles the shape of the spathe of an Arum plant. Diagnosis: Males resemble only those of V. montesta (fig. 163) and V. poas (fig. 193) in having a tube-shaped embolus, bent approximately 90° prolaterad with an opening skewed dorsally and a distinct conductor with a broadened flat, base and distally with a long, back- ward-pointed spur (also present but short in V. cerrado, fig. 343). They differ in having an elongated hook-shaped distal tip of the conductor (rather than broad, hook shaped in V. poas or simple, pointed in V. montesta). Females can be separated from those of all other species by the short stalked, leaf-shaped anterior genitalic process and the moderately convoluted, distally subspherically enlarged posterior process (fig. 187). Male (PBI_OON 31104, figs. 173–182): Total length 1.84. Sternum microsculpture medially and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum moderately concave (in anterior view). Postepigastric scutum with posterior margin moderately concave. Leg spination: femur I p0-1-1; tibiae: I p1-1-0, v4-2-2, r1-0-0; II v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Sperm pore oval. Cymbial cone narrow, cone shaped. Embolus tube shaped, elongated, evenly curved prolaterad, tip with rebordered, oval opening and distally strongly elon- gated, triangularly pointed protrusion, proximal of opening with slightly elevated protuberance; conductor basally broad, lamelliform, enlarged distally, T-shaped, with simple, pointed, furrowed, proximal branch twice as long as elongated hook-shaped distal branch. Female (PBI_OON 31002, figs. 183–187): Total length 2.00. Leg spination: femora: I p0-1- 1; II p0-0-1; tibiae: I p1-1-0, v4-2-2, r1-0-0; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Anterior process, plate, and posterior sclerite moderately visible through epigastric and post- epigastric scuta. Median protruding part of large genitalic plate as long as wide; anterior geni- talic process short stalked, leaf shaped, approximately half length of posterior genitalic process; field of filiform glands on small basal plate of anterior genitalic process not observed; posterior genitalic process originating from small W-shaped plate, long, tube shaped, basally stronger sclerotized (with ring of glands), distally moderately bent, subspherically enlarged.

Varioonops poas, new species Figures 188–202 Note: Males and females have not been collected together, show some somatic differences (e.g., microsculpture on the sternum, size), and may be mismatched. Types: Male holotype and male paratype collected at the camping area at Volcán Poás, Heredia, Costa Rica (C. Víquez, E. Ulate, May 10, 2005), deposited in INBIO (PBI_OON 31082). Etymology: The specific name is a noun in apposition taken from the type locality. Diagnosis: Males resemble only those of V. montesta (fig. 173) and V. spatharum (fig. 178) in having a tube-shaped embolus, bent approximately 90° prolaterad with an opening skewed dorsally and a distinct conductor with a broadened flat base and distally with a long, backward- pointed spur (also present but short in V. cerrado, fig. 343). They differ in having a broad, flat hook-shaped distal tip of the conductor (rather than elongated, hook shaped in V. spatharum or simple, pointed in V. montesta). Females can be separated from those of all other species by the skewed, spoon-shaped, narrowly stalked anterior genitalic process and the distally con- spicuously trapezoidal, enlarged posterior process (fig. 202). Male (PBI_OON 31082, figs. 188–196): Total length 2.05. Sternum microsculpture medi- ally and in furrows, surface evenly granulated.

Cymbial cone narrow, elongated, originating from pit. Embolus tube shaped, elongated, smooth (distally with some short lon- gitudinally scattered ribs), curved ventroprolaterad; tip with oval opening, margin moderately rebordered, distally elongated, subrectangular plate; conductor basally broad, lamelliform, enlarged, distally divided into broad, flat hook, pointing posteriad, and backward-pointed spur- shaped, furrowed projection. Female (PBI_OON 31043, figs. 197–202): Total length 1.80. Sternum surface loosely, coarsely granulated. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I p1-1-0, v4-2-2, r1-0-0; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Median protruding part of large genitalic plate almost twice as long as wide; anterior genitalic process skewed, spoon shaped, narrowly stalked, as long as posterior genitalic process; field of filiform glands on small basal plate of anterior genitalic process present but inconspicuous; posterior genitalic process basally broad, tube shaped, elongated, distally conspicuously trapezoidal, enlarged.

The tortuguero group Varioonops varablanca, new species Figures 203–217 Type: Male holotype taken at an elevation of 1450–1550 m at a site 9 km northeast of Vara Blanca, 10.23333°N, 84.10000°W, Heredia, Costa Rica (C. Víquez, Feb. 19, 2005), deposited in INBIO (PBI_OON 31106). Etymology: The specific name is a noun in apposition taken from the type locality. Diagnosis: Males resemble only those of V. tortuguero, V. veragua, and V. ramila in having the embolus tip abruptly bent prolaterad and in having a simple long conductor originating ventroprolateral at the embolus base. They differ in the very distinct, narrow, tube-shaped conductor which is longer than the embolus (fig. 208, rather than spindle shaped in V. tortu- guero, figs. 72, 73, basally flat in V. veragua, fig. 242, or completely flattened in V. ramila, fig. 253, and all shorter than embolus). Females differ from those of all other species by the broad- stalked, mushroom-shaped anterior genitalic process and the dorsally bent, moderately club- shaped posterior process (fig. 217). Male (PBI_OON 31106, figs. 203–211): Total length 1.53. Sternum microsculpture medi- ally and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum moderately concave (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femur I p0-1-1; tibiae: I v4-2-2; II v4-2-1p; metatarsi I, II p1-0-0, v2-2- 2. Sperm pore oval. Cymbial cone not detected. Embolus tube shaped, elongated, smooth, basally moderately curved, distally abruptly bent; tip with simple oval opening and distally elongated, spur-shaped, pointed tip; conductor smooth, narrow, branch shaped, distally mod- erately flattened, pointed, distinctly longer than embolus. Female (PBI_OON 31036, figs. 212–217): Total length 1.78. Leg spination: femora: I p0-1- 1; II p0-0-1; tibiae: I p1-1-0, v4-2-2, r1-0-0; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Median protruding part of large genitalic plate as long as wide; anterior genitalic process broad stalked, with irregularly enlarged apex, mushroom shaped, longer than posterior genitalic pro- cess; field of filiform glands on small basal plate of anterior genitalic process conspicuous; posterior genitalic process moderately club shaped, bent dorsally, distally folded, appearing heart shaped, glands visible.

Ubick, Apr. 17–23, 1983), deposited in CAS (PBI_OON 3611). Etymology: The specific name is a noun in apposition taken from the type locality. Diagnosis: Males resemble only those of V. varablanca (fig. 208), V. veragua (fig. 242), and V. ramila (fig. 253) in having the embolus tip abruptly bent prolaterad and in having a simple, long conductor originating ventroprolaterally at the embolar base. They differ in having a very distinct, spindle-shaped conductor (fig. 73), rather than a narrow, branch-shaped one, that is longer than the embolus in V. varablanca, basally flat in V. veragua, and completely flattened in V. ramila. Females are most similar to those of V. veragua (fig. 247) but differ from those and all other species by the long, narrow-stalked, distally bulky, enlarged anterior genitalic process and the broad, club-shaped, unconvoluted posterior process (figs. 102, 232). Male (PBI_OON 3611, figs. 61–90, 218–226): Total length 1.45. Sternum microsculpture medially and in furrows, sternum surface evenly, coarsely granulated.

Varioonops veragua, new species Figures 233–247 Types: Male holotype, male paratype, and three female paratypes taken in a mini-Winkler trap in a rainforest on the El Pity trail in the Veragua Rainforest, Limón, Costa Rica (M. Solis; Mar. 19, 2009), deposited in INBIO (PBI_OON 49175). Etymology: The specific name is a noun in apposition taken from the type locality. Diagnosis: Males resemble only those of V. tortuguero (figs. 71–75), V. varablanca (fig. 208), and V. ramila (fig. 253) in having the embolus tip abruptly bent prolaterad and in having a simple, long conductor originating ventroprolaterally at the embolar base. They differ in hav- ing the conductor basally flat (fig. 242), rather than spindle shaped in V. tortuguero, narrow, branch shaped, and longer than the embolus in V. varablanca, and completely flattened in V. ramila. Females resemble those of V. tortuguero but differ those of all other species by the long, narrow-stalked, distally enlarged, and subcircular anterior genitalic process and the long, tube- shaped, distally spherically enlarged, unconvoluted posterior process (fig. 247).

Dybas; Apr. 1, 1959), deposited in FMNH (33655, PBI_OON 10157). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Males resemble only those of V. tortuguero (figs. 71–75), V. varablanca (fig. 208), and V. veragua (fig. 242) in having the embolus tip abruptly bent prolaterad and in having a simple, long conductor originating ventroprolaterally at the embolar base. They differ in hav- ing the conductor completely flat (figs. 253, 257), rather than distinctly spindle shaped in V. tortuguero, narrow, branch shaped, and longer than the embolus in V. varablanca, and basally flattened inV. veragua. Females resemble those of V. heredia but differ from those of all other species by the long-stalked, distally bulbous, enlarged anterior genitalic process and the very short, distally subspherical, enlarged, and gland-bearing posterior process (fig. 262). Male (PBI_OON 37759, figs. 248–257): Total length 1.38. Sternum fused to carapace, microsculpture everywhere but front, laterally less dense, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum straight (in anterior view). Postepigastric scutum with posterior margin moderately concave. Leg spination: femur I p0-1-1; tibiae: I v4-2-2; II v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Sperm pore relatively large, oval. Embolus tube shaped, elongated, evenly curved prolaterad, dorsally moderately carinated; tip with simple oval open- ing and distally elongated plate (broken off on SEM picture); conductor lamelliform, originat- ing ventroprolaterally on same base as embolus, bent prolaterad, distally narrowing, with pointed tip, moderately shorter than embolus. Female (PBI_OON 10405, figs. 258–262): Total length 1.70. Leg spination: femora: I p0-1- 1; II p0-0-1; tibiae: I p1-0-0, v4-2-2, r1-0-0; II v4-2-2; metatarsi I, II p1-0-0, v2-2-2. Anterior, posterior sclerite, plate moderately visible through epigastric and postepigastric scuta. Median protruding part of large genitalic plate longer than wide; anterior genitalic process long stalked, with bulbous, enlarged apex, as long as posterior genitalic process; field of filiform glands at base of anterior genitalic process conspicuous; posterior genitalic process with short connect- ing duct, distally subspherical, bearing glands.

The sansidro group Varioonops heredia, new species Figures 263–277 Note: The male and female specimens described here were collected at the same locality, but not at the same time. There are some obvious somatic differences between them in sternum microstructure and size, and their association may be erroneous. Type: Male holotype taken at an elevation of 1450–1550 m at a site 9 km northeast of Vara Blanca, 10.23333°N, 84.10000°W, Heredia, Costa Rica (C. Víquez; Apr. 15, 2005), deposited in INBIO (PBI_OON 31105). Etymology: The specific name is a noun in apposition taken from the type locality. Diagnosis: Males resemble only those of V. sansidro (figs. 286–288) in having a basally strongly bent and more distally only moderately bent, smooth, tube-shaped embolus in combination with a very short, flat, triangular conductor (figs. 270, 272). A similar con- ductor is also present in males of V. girven, which differ in having a more evenly bent embolus with longitudinal furrows (fig. 313). The distinctly shorter conductor and the moderately pointed embolus tip with its opening directed posteriorly (rather than an irreg- ularly formed opening directed anteriorly) are characters that separate males from those of V. sansidro. Females resemble those of V. ramila (fig. 262) but differ from those and of all other species by the long-stalked, distally only moderately enlarged anterior genitalic process and the very short (even shorter than in V. ramila ), subspherical, flask-shaped, gland-bearing posterior process (fig. 277). Male (PBI_OON 31105, figs. 263–272): Total length 1.66. Sternum microsculpture medi- ally and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum straight (in anterior view). Postepigastric scutum with posterior margin concave. Leg spination: femur I p0-1-1; tibiae I, II v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Cymbial cone longitudinally ribbed. Sperm pore relatively large, oval. Embolus tube shaped, elongated, curved ventroprolaterad, narrowing toward tip; tip posteroventrally furrowed, opening simple, oval, distally elongated, truncated; conductor very short, flat, triangular. Female (PBI_OON 31042, figs. 273–277): Total length 2.03. Sternum microsculpture everywhere but front (even though less dense laterally). Leg spination: femur I p0-1-1; tibiae: I p1-1-0, v4-2-2, r1-0-0; II p0-1-0, v4-2-2; metatarsi I, II p1-0-0, v2-2-2. Anterior, posterior sclerite, plate moderately visible through epigastric and postepigastric scuta. Median protrud- ing part of large genitalic plate longer than wide; anterior genitalic process long stalked, with moderately enlarged apex, distinctly longer than posterior process; field of filiform glands at base of anterior genitalic process conspicuous; posterior genitalic process flask shaped, with short connecting tube, distally bearing glands. 2013 BOLZERN AND PLATNICK: VARIOONOPS 39

Varioonops sansidro, new species Figures 278–307 Note: In the dissected female genitalia, some morphological differences are obvious (figs. 302–304); they are regarded as intraspecific variation. Types: Male holotype, male paratype, and three female paratypes from in cloud-forest litter taken at an elevation of 1800 m at a site at km 117 of the Interamerican Highway, 19 km north of San Isidro, 9.46666°N, 83.70555°W, San José, Costa Rica (R. Anderson; Feb. 15, 1998), deposited in AMNH (PBI_OON 49184). Etymology: The specific name is a noun in apposition, contracted from the type locality. Diagnosis: Males resemble only those of V. heredia (fig. 272) in having a basally strongly bent and more distally only moderately bent, smooth, tube-shaped embolus in combination with a very short, flat, triangular conductor (figs. 287, 291). A similar conductor is also present in V. girven, which differs in having a more evenly bent and longitudinally ribbed embolus (fig. 313). The distinctly longer conductor and the stepped, truncated, plate-shaped projection at the embolus tip, with an irregularly formed opening pointing anteriorly (rather than a moder- ately pointed embolus tip with its opening pointing posteriorly) are characters that separate males from those of V. heredia. Females differ from those of all other species by having a nar- row, long-stalked, distally variably enlarged anterior genitalic process and a long, duct-shaped, distally subspherically enlarged, moderately but variably bent posterior process with many suboval glands attached at the duct, producing a ribbed appearance (figs. 301–304, 306, 307). Male (PBI_OON_49184, figs. 278–292): Total length 1.73. Sternum microsculpture medially and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum concave (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I v4-2-2; II v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Sperm pore oval. Cymbial cone distally moderately elongated. Embolus tube shaped, elongated, smooth, almost orthogonally bent prolaterad, opening subtriangular, distally with stepped, truncated, plate-shaped projection; conductor simple, flat, triangular, less than ⅓ of embolus length. Female (PBI_OON_49184, figs. 293–307): Total length 1.87. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-2; metatarsi I, II p1-0-0, v2-2-2. Median protruding part of large genitalic plate as long as wide; anterior genitalic process long, narrow stalked, distally enlarged, bulbous (variable, figs. 301–304), shorter than posterior pro- cess; field of filiform glands on small basal plate of anterior genitalic process conspicuous; posterior genitalic process long duct with subspherically enlarged distal end, moderately bent (variable), many suboval glands attached at duct producing a ribbed appearance.

Ungrouped Species from Costa Rica and Panama Varioonops girven, new species Figures 308–322 Note: Males and females have not been collected together; even though there is a good match in somatic morphology, the affiliation of the two sexes is tentative and remains uncertain. Types: Male holotype and male paratype taken at an elevation of 250–350 m at a site 11 km ESE of La Virgen, Heredia, Costa Rica (C. Víquez; Feb. 18, 2004), deposited in INBIO (PBI_OON 31100). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Males differ from those of all other species in having a small, flat, triangular conductor (similar to that found in V. heredia, fig. 272, and V. sansidro, figs. 286–288) in combi- nation with a broad, longitudinally ribbed, tube-shaped embolus with an oval opening that is skewed dorsad (fig. 313). Females can be separated from those of all other species by the distinct, conical, flask-shaped posterior genitalic process, distally bearing suboval glands (fig. 322). Male (PBI_OON 31100, figs. 308–316): Total length 1.41. Sternum fused to carapace, microsculpture everywhere but front, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum concave (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femur I p0-1-1; tibiae I, II v4-2-1p; metatarsi: I p1-0-0, v2-2-2; II v2-2- 2. Sperm pore relatively large, triangular, with rounded angles. Embolus tube shaped, elon- gated, longitudinally ribbed on ventroprolateral side, curved ventroprolaterad, basally broad, moderately tapering toward tip, tip with slanted oval opening; conductor short, triangular, lamelliform, distally pointed, much shorter than embolus. 44 American Museum Novitates No. 3791

Varioonops cerrado, new species Figures 338–352 Note: Males and females have not been collected at the same locality, but given their simi- lar somatic morphology and the proximity of their sites, it is likely that the two specimens described here are conspecific. Type: Male holotype from moss on rocks with sphagnum taken in a ravine in a cloud forest at an elevation of 1460 m at Cerro Colorado, Chiriquí, Panama (W. Suter; Jan. 18, 1981), deposited in FMNH (33670, PBI_OON 10172). Etymology: The specific name is a noun in apposition, contracted from the type locality. Diagnosis: Both sexes can be separated from those of the other known species by their distinct genitalia. The most salient characters are the overall shape of the male bulb (figs. 344–346), the spoon-shaped conductor with a short, backward-pointing appendage (a long, backward-pointing spur is present in males of the montesta group, figs. 163, 182, 193), and the posterior genitalic process of females having a relatively long connection duct with a spherical apex, in combination with a strongly sclerotized anterior process (fig. 352). Male (PBI_OON 10172, figs. 338–348): Total length 1.87. Sternum microsculpture medi- ally and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum straight (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femur I p0-1-1; tibia I v4-2-2; metatarsi: I p1-0-0, v2-2-2; II missing. Sperm pore relatively large, oval. Embolus tube shaped, elongated, distally not tapering, discontinuously curved prolaterad; distal half longitudinally ribbed (tip may be broken off in SEM sample); conductor basally narrow, medially wide, lamelliform, distally spoon shaped, prolaterally with backward-folded, pointed appendage, shorter than embolus. Female (PBI_OON 10175, figs. 349–352): Total length 2.13. Leg spination: femora: I p0-1- 1; II p0-0-1; tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2.

Species from Colombia Varioonops edvardi, new species Figures 353–367 Types: Holotype male, 14 male paratypes, and 12 female paratypes taken at an elevation of 1563 m at a site between San Pedro and San Javier, Sierra Nevada de Santa Marta, Magda- lena, Colombia (J. Kochalka; Mar. 29, 1975), deposited in AMNH (PBI_OON 37055). Etymology: The specific name is a patronym in honor of the Norwegian painter Edvard Munch. The anterior view of the male abdomen resembles the screaming face in Munch’s most famous painting, “The Scream.” Diagnosis: Males differ from the other known species by the narrow, lamelliform conduc- tor equipped distally with three short, pointed spikes (similar to V. ramila, fig. 253, but those males lack distal spikes and have a very differently shaped bulb). Females are similar to those of V. sinesama (fig. 375) but differ from those and the other species in having a long-stalked anterior genitalic process (rather than a shorter, broader one as in V. sinesama) in combination with a pocket-shaped, subrectangular, and distally rounded posterior genitalic process (rather than long and finger shaped in V. sinesama). Male (PBI_OON 37055, figs. 353–363): Total length 1.57. Sternum microsculpture every- where but front, laterally less dense, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum concave (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femur I p0-1-1; tibiae: I v4-2-2; II v4-2-1p; metatarsi I, II v2-2-2. Sperm pore triangular, with rounded angles. Embolus tube shaped, elongated, curved prolaterad; tip with simple subcircular opening, ventrally with additional opening; conductor narrow, lamel- liform, originating prolaterally on same base as embolus, distally with three short, pointed spikes, almost as long as embolus. Female (PBI_OON 37055, figs. 364–367): Total length 1.76. Leg spination: femur I p0-1-1; tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Median protruding part of large genitalic plate blunt, triangular; anterior genitalic process long stalked, with broad- ened apex, longer than posterior process; field of filiform glands on small basal plate of anterior genitalic process conspicuous; posterior process elongated, pocket shaped, subrectangular, dis- tally rounded.

Varioonops sinesama, new species Figures 368–375 Type: Female holotype from leaf litter and moss taken at an elevation of 2200 m at San Lorenzo, northern Sierra Nevada de Santa Marta, Magdalena, Colombia (H.-G. Mueller, June 20, 1985), deposited in MHNG (PBI_OON 49205). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Females resemble those of V. edvardi but differ from those and the other known species in having a short, broad-stalked anterior genitalic process (rather than a longer one as in V. edvardi) in combination with a long, finger-shaped posterior genitalic process (fig. 375); rather than a pocket-shaped, subrectangular, distally rounded one as in V. edvardi. Male: Unknown. Female (PBI_OON 49205, figs. 368–375): Total length 2.05. ALE separated by moderately more than their diameter. Sternum microsculpture medially and in furrows, surface loosely, coarsely granulated. Leg spination: femur I p0-1-1; tibiae: I p1-1-0, v4-2-2, r1-0-0; II p0-1-0, v4-2-1p; metatarsi I, II p1-0-0, v2-2-2. Median protruding part of large genitalic plate wider than long; anterior genitalic process short, broad stalked, bulbous, apex irregularly enlarged, moderately longer than posterior process; field of filiform glands at base of anterior genitalic process conspicuous; posterior process simple, finger shaped, blunt, distal half bearing glands. Other Material Examined: None. Distribution: Known only from the type locality in Magdalena, Colombia.

Species from Venezuela The yacambu group Varioonops yacambu, new species Figures 383–397 Types: Male holotype and two female paratypes from cloud-forest litter taken at an elevation of 1850 m at a site 6.4 km southeast of Sanare, Yacambú National Park, 9.69750°N, 69.64916°W, Lara, Venezuela (R. Anderson; May 17, 1998), deposited in AMNH (PBI_OON 49204). Etymology: The specific name is a noun in apposition taken from the type locality. Diagnosis: Males resemble those of V. trujillo (fig. 408) and V. pittieri (fig. 418) in having a basally fused embolus and conductor with a pronounced base, but differ from those and all other species in having a slender embolus (figs. 392, 393) rather than the basally broadly stepped and distally more robust one found in V. trujillo or the markedly different one found in V. pittieri, and a distinctly fork-shaped conductor with three short, pointed spikes (fig. 393). Females can easily be recognized by the narrow-stalked, dendriform anterior genitalic process with its very broadly enlarged apex (rather than broad and long stalked in V. pittieri, fig. 427) and the long, tube- shaped, distally bent and subspherically enlarged posterior process (fig. 397). Male (PBI_OON 49204, figs. 383–393): Total length 1.77. Sternum microsculpture medi- ally and in furrows, surface loosely, coarsely granulated.

Grande, Aragua, Venezuela (S., J. Peck; Feb. 19–27, 1971), deposited in FMNH (males: PBI_ OON 10119, female: PBI_OON 37841). Etymology: The specific name is a patronym in honor of the Swiss naturalist and botanist Henri Pittier (1857–1950), who is also the eponym of the Parque Nacional Henri Pittier, in which the type locality is situated. Diagnosis: Male and female specimens can easily be separated from those of all other species by the uniquely shaped embolus and conductor (figs. 418, 422) and the broad, long- stalked dendriform anterior genitalic process (rather than the narrow-stalked dendriform pro- cess found in V. yacambu, fig. 397) in combination with the short, pocket-shaped posterior process (fig. 427). Male (PBI_OON 10119, figs. 413–422): Total length 1.16. Sternum microsculpture medi- ally and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum straight (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femur I p0-1-1; tibiae: I p1-0-0, v4-2-2; II v4-2-1p; metatarsi: I v2-2-2; II p1-0-0, v2-2-2. Sperm pore relatively large, subtriangular. Embolus broad, tube shaped, elongated, almost orthogonally bent prolaterad, surface transversely ribbed; tip truncated, moderately enlarged, with inverse U-shaped opening; conductor originating prolateral of embolar base, basally broad, flat, triangular, distally narrowed, irregularly flattened with four anteriorly directed spikes, most proximal spike distinctly larger, longer than others, conductor half as long as embolus.

Diagnosis: Males can be separated from those of all other species by the distally bifid conductor with a thorn-shaped process and a rounded plate with a recessed opening (figs. 233, 237). Females can be recognized by the spherical gland-bearing posterior genitalic process with an extraordinary short connecting duct (fig. 442, anterior genitalic process detached from plate in this image). Male (PBI_OON 49201, figs. 428–437): Total length 1.63. Sternum microsculpture medi- ally and in furrows, surface loosely, coarsely granulated. Anterodorsal margin of epigastric scutum straight or moderately convex (in anterior view). Postepigastric scutum with posterior margin straight. Leg spination: femur I p0-1-1; tibiae: I v4-2-2; II v4-2-1p; metatarsi I, II p1-0- 0, v2-2-2. Sperm pore relatively large, circular. Embolus tube shaped, elongated, evenly curved ventroprolaterad; tip with simple, stepped, oval opening; conductor basally broad, lamelliform, distally divided into short, rounded plate with recessed opening and long, thorn-shaped pro- cess, longer than embolus. Female (PBI_OON 49201, figs. 438–442): Total length 1.9. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I p1-0-0, v4-2-2, r1-0-0; II p0-1-0, v4-2-1p or v4-2-2; metatarsi I, II p1-0-0, v2-2-2.

Other Material Examined: None. Distribution: Venezuela (Táchira).

Varioonops parlata, new species Figures 443–473 Types: Male holotype and two female paratypes from streamside shrub litter taken at an elevation of 2950 m on the Páramo La Culata, 18.5 km NE Mérida, 8.74277°N, 71.06222°W, Mérida, Venezuela (R. Anderson; May 25, 1998), deposited in AMNH (male and one female: PBI_OON 49200, female: PBI_OON 49203). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: Male and female specimens can be separated from those of all other species by the only moderately granulated carapace (fig. 443–445, 459, 460) and the only indistinctly granulated sternum (fig. 446, 462). Males have a unique, wrench-shaped conductor (figs. 456, 457) and anteromedially modified endites (fig. 447). Females can be recognized by the goblet- shaped anterior genitalic process (figs. 470, 471). Male (PBI_OON 49200, figs. 443–458): Total length 1.92. Carapace with moderate granu- lation. Clypeus low, ALE separated from edge of carapace by less than their radius. ALE, PME subequal, larger than PLE. Sternum microsculpture medially and in furrows, surface indis- tinctly granulated (moderately reduced).

Varioonops potaguo, new species Figures 474–488 Note: Males and females have been collected at the same locality, but not at the same time. Based on somatic morphology, it is likely that the described male and females are conspecific. Type: Male holotype from sifted insect bait taken at an elevation of 400 m at a site 35 km north of Altagracia, Parque Nacional Guatopo, Agua Blanca, Miranda, Venezuela (S., J. Peck; June 3, 1987), deposited in AMNH (PBI_OON 1312). Etymology: The specific name is a noun in apposition, an anagram taken from the type locality. Diagnosis: Males and females of this smallest species can be separated from those of all other species by the very broad, lamelliform conductor (figs. 479) and the somewhat medially interrupted, large genitalic plate, which is even visible ventrally at the epigynal area (figs. 486– 488). In addition, the field of distally filiform glands at the base of the anterior genitalic process is conspicuously expressed (fig. 488). Male (PBI_OON 1312, figs. 474–482): Total length 1.08. Sternum fused to carapace, microsculpture everywhere but front, surface loosely, coarsely granulated. Anterodorsal margin 2013 BOLZERN AND PLATNICK: VARIOONOPS 63

Varioonops grancho, new species Figures 376–382 Type: Female holotype collected at Rancho Grande (presumably the well-known Estación Biológica Rancho Grande, northwest of El Limon, south of the Parque National Herni Pittier, Aragua), Venezuela (M. Paoletti; Sept. 29, 1980), deposited in AMNH (PBI_OON 1692). Etymology: The specific name is a noun in apposition, a shortened anagram taken from the type locality. Diagnosis: The female resembles that ofV. sinesama (fig. 375) in having a short, broad- stalked anterior genitalic process but differs from those and other species in having a short, weakly sclerotized, pocked-shaped. elongated posterior process (fig. 382). Male: Unknown. Female (PBI_OON 1692, figs. 376–382): Total length 1.91. Sternum microsculpture medi- ally and in furrows, surface evenly, coarsely granulated. Leg spination: femora: I p0-1-1; II p0-0-1; tibiae: I p1-1-0, v4-2-2; II p0-1-0, v4-2-2; metatarsi I, II p1-0-0, v2-2-2. Median pro- truding part of large genitalic plate wider than long; anterior genitalic process short, broad stalked, bulbous, moderately longer than posterior process; glands at base of anterior genitalic process inconspicuous; posterior genitalic process elongated, pocked shaped, weakly sclerotized. Other Material Examined: None. Distribution: Known only from the holotype from Venezuela. 2013 BOLZERN AND PLATNICK: VARIOONOPS 65
